85 irocz tpi no fan switch
Someone please help!! OK I have an 85 irocz with tpi and single radiator fan. I know everyone says the fan is turned on by the fan switch which is located between the 6 and 8 head... my car has a factory plug in that location and no green/white wire in that location. The green/white wire I have goes straight to my fan relay. I know for a fact my fan works and my relay works cause when I add a ground to the green/white wire on the relay, the fan turns on. Also it turns on when I take the connection off of the high pressure switch to the ac. Please advise where I'm screwing up. Why is my fan not turning on and what activates the relay. FYI I tried removing the plug to install a fan switch but stripped out the inside of the plug so it's stuck. Thank you in advance
